There are various detection elements such as reed switches, Hall elements, MR elements, and TMR elements, but our company utilizes a unique "saturable coil" for sensing. Since the outputs are generated separately for the N and S poles, the range of applications expands depending on the combination of magnets used. By selecting the appropriate magnets, the detection distance can be extended to over 100mm. It can detect magnets underground. Depending on the application, it can also sense within the soil of golf courses, baseball fields, and various sports venues. For example, if the S pole is detected for positioning, it can decelerate, and if the N pole is detected, it can stop. Normally, it operates under N pole control, and if the S pole is detected, it can trigger an unconditional emergency stop, all with a single switch. By using N and S magnets on tags, binary codes can be created, making it useful for sorting tasks. Since it detects the magnetic field generated by the magnets, it is not affected by dirt or dust. Sample lending is available. It can be used in various scenarios, from magnetic polarity discrimination and non-contact detection to inspection jigs on manufacturing lines. Custom options, such as fully submerged types, are also possible while maintaining the electrical specifications.

At a wood processing manufacturer, there were frequent troubles with the conveyor for transporting "particle boards (3×6 feet × 80 sheets/1 lot)." There were requests such as, "The conveyor's top chain reaches its material lifespan at 1,650 rotations, so we want to replace it before then," and "We want a sensor that can reliably count so that we can ensure it is worn out by 1,650 rotations." Therefore, we installed the magnetic proximity switch "DW-350" made by Makome Research Institute under the conveyor and attached the magnetic body "SMG-100N" to the top chain. As a result of the improvement, by installing the "DW-350," we were able to manage the count of the top chain, transitioning from reactive maintenance to preventive maintenance. *For more details, please refer to the PDF document or feel free to contact us.

We have been using a stirrer for drug formulation, and until now, we managed the mixing process by timing it with the stirrer's button. Although we adjust the stirring time based on seasonal conditions, managing it by time means that any malfunction could lead to insufficient mixing and result in product defects. There have been requests such as "I want to monitor whether the stirrer is definitely running" and "I want to manage the stirrer's rotation speed and shorten the changeover time." We installed the magnetic proximity switch "DW-100" manufactured by Makome Research Institute on the stirrer, placing the "DW-100" next to the stirrer shaft, and affixing the magnetic bodies "SMG-100N" and "SMG-100S" around the shaft. As a result of this improvement, by installing the "DW-100," we can now manage the count of the stirrer, making the changeover process smoother. *For more details, please refer to the PDF document or feel free to contact us.

■It uses an optical sensor, but it requires regular cleaning, which is a hassle. ■It uses a mechanical switch, but due to the high number of operations, the replacement frequency is high. ■I want to detect from a slightly farther distance. ■I want to detect through obstacles (non-magnetic materials). There are environments suitable for magnetic sensors. Furthermore, magnets have N-pole and S-pole polarities. In general proximity sensors, only ON/OFF signals can be extracted, but with magnetic sensors, N-pole and S-pole signals can be extracted individually. Depending on the idea, it is possible to create hardware and programs. As application examples: ◎ Deceleration (N-pole) / Stop (S-pole) ◎ Stop (N-pole) / Emergency Stop (S-pole) ◎ Addition (N-pole) / Subtraction (S-pole) It can also be used to treat address codes as three-value codes. Why not switch to a maintenance-free Macome sensor? *For more details, please download the PDF or contact us.*

Our unique technology enables high-sensitivity transmission, allowing a distance of up to 170mm between the transmitter and receiver. Additionally, due to the electromagnetic induction method, it is not affected by non-metallic obstacles between the transmitter and receiver. There is also no issue with dirt on the equipment. 【Features】 - The ST-3726E is an electromagnetic induction signal transmission device that uses the transmitter STT-3726E and the receiver STR-3726E as a pair. - It can transmit up to 4 channels of switching (ON/OFF) signals or contact signals. - It has 4 outputs with NPN transistor open collector output. Operation with separate power supplies for the transmitter and receiver is possible.

The N and S poles of the magnet can be visually identified. When magnetic fields are detected, the LED lights up red for the N pole and blue for the S pole (when using the DW-350). Additionally, it is equipped with individual transistor outputs, making it easy to apply in circuits. It operates from DC 10V, so it can also be powered by connecting batteries in series. You can use it for various applications, from elementary school experiments to sophisticated control systems, depending on your ideas. * Powerful magnets can be obtained even at 100 yen shops, so feel free to try various things.

This is a magnetic proximity sensor with a separate detection head and detector. It detects the magnetic flux of a dedicated magnet and can obtain an analog signal proportional to the magnetic flux density, which is used for switching output. With a detection distance of 1 to 3 mm and a repeatability accuracy of ±1 μm, it enables precise on/off operations, achieving high-precision positioning. Of course, since it uses a magnetic detection method, it can operate stably and accurately even in harsh environments with dirt and dust. 【Main Features】 ■ Type with a separate detection head and detector ■ Power supply voltage: 'LS-106S' supports DC +12V, 'LS-127' supports DC +24V

■ It uses an optical sensor, but it requires regular cleaning, which is a hassle. ■ The optical sensor cannot be used in environments where dust and mist are constantly present. ■ It uses a mechanical switch, but due to the high number of operations, it needs to be replaced frequently. ■ I want to avoid mechanical switches for waterproofing reasons. ■ I want to detect from a bit further away; detection over 100mm is possible. ■ I want to detect through obstacles (as long as they are non-magnetic materials, there is no problem). ■ Detection is not possible due to freezing or condensation. Are you facing any of these issues? There are environments suitable for magnetic sensors. Additionally, magnets have N-pole and S-pole polarities. While general proximity switches can only output ON/OFF signals, magnetic sensors can individually output signals for N-pole and S-pole. With some creativity, hardware and programming are also possible. For example, you can use it for deceleration (N-pole), stop (S-pole), stop (N-pole), emergency stop (S-pole), and you can also use address codes as a ternary code. Completely non-contact. Would you like to switch to a maintenance-free, long-lasting Makome sensor? Length measurement, rotational measurement, direction of movement detection.
